Fed­erico Rosa, an Ital­ian na­tional, had been fac­ing charges that he pro­vided or ad­min­is­tered banned sub­stances to Jep­too and an­other lit­tle-known Kenyan run­ner, with some of the al­le­ga­tions dat­ing back as far as 2004.

Rosa said he had been given back his pass­port by a court in Nairobi and was free to go. He had been out on bail ahead of Tues­day’s court hear­ing.

“There is no wit­nesses. There is noth­ing against me. There is no case. This is one of the best days of my life,” Rosa told The As­so­ci­ated Press in a phone in­ter­view.

Rosa was freed, but pros­e­cu­tors said they would in­ves­ti­gate fur­ther and he could be re-ar­rested and re-charged.

Pros­e­cu­tors had said that Rosa was com­plicit in Jep­too’s dop­ing in 2014, when he was her man­ager. Jep­too, once the lead­ing women’s marathon run­ner in the world, tested pos­i­tive for EPO in an out-of-com­pe­ti­tion test that year. She was ini­tially banned for two years, but her pun­ish­ment was dou­bled to four years by the Court of Ar­bi­tra­tion for Sport last month. That CAS rul­ing also ap­peared to vin­di­cate Rosa, with the Swiss-based court not­ing in its find­ings that Jep­too had hid­den her dop­ing from her man­age­ment and coach­ing team at the time. Rosa ended his association with Jep­too af­ter she failed the dop­ing test.Al­though Jep­too was named as a com­plainant by pros­e­cu­tors in the Kenyan crim­i­nal case, Rosa dis­puted that his client had ever ac­cused him of in­volve­ment in her dop­ing. Charges that Rosa helped ad­min­is­ter banned sub­stances to Eli­jah Kiprono Boit, a for­mer 800-me­ter run­ner who com­peted at the world youth cham­pi­onships in 2001 and 2004, were also dropped. Rosa was ac­cused of help­ing Boit dope be­tween 2004-08.
